I'm planning to figure out if it's at all feasible with gstreamer.
This feature needs a guarantee that seeking is synchronized to the
clock, specifically that if we issue a seek event to the point x in a
file at clock time y, then at any time y+a in the future, the playback
is exactly at x+a. Nothing I've seen in gstreamer documentation
indicates this, it might be that seeking happens ad-hoc, discarding
the timestamp of the seek event.
